The Mamiya 180mm f/4.5 is a compact mid range telephoto lens, and the most popular telephoto for the 6x7cm format. Mamiya lenses are quality controlled at all stages. They are engineered for professional use. Mamiya manufactures its own glass and coats the lens elements using Mamiya's proprietary multi-coating process, increasing light transmission, dramatically reducing flare, and ensuring crisp, clean whites and vibrant natural colors. A popular portrait lens for the Mamiya RB67 cameras, it yields a good camera to subject distance, slight flattening of portrait subjects, and exceptional sharpness.
